My brand new DVX-100 makes a clicking sound when I rock it gently forward and backward. I have not heard of this and hope that it is indeed normal. I have a wedding project to work on tomorrow so I will find out one way or another. And no I did not book a wedding with a brand new, unproven camera. :) This project is to be shown at the wedding some months from now. If we can't shoot tomorrow, no big deal.
